The Dynamics of Drinking and Driving in the U.s.: the Role of Social Forces and the Role of Law
نویسندگان
چکیده
The dynamics of drinking and driving can be adequately described using the fraction of accidents involving drivers who had been drinking. Evaluating drunk driving legislation using this measure implicitly controls for unobservable “general risk” influences on traffic safety, reducing bias and variability in estimates of laws’ effects, especially in the early studies that influence lawmakers most strongly. Using this approach, we find that the widespread enactment of seven key drunk driving laws explains one-fifth of the reduction in drinking and driving since 1982, comparable to the effects of demographics and alcohol consumption, and less than the effect of “social forces.” JEL Codes: I18, K14, N42
